Adelaida Maria Ruiz (born October 17, 1988) is an American professional boxer who has held WBC female super-flyweight title since November 2025.

Professional career

Ruiz made her professional debut on April 21, 2017, scoring a four-round unanimous decision (UD) victory against Rebecca Light at the Quiet Cannon in Montebello, California.[2]

After compiling a record of 9–0 (4 KOs), she faced reigning champion Sonia Osorio for the WBC female interim super flyweight title on March 20, 2021, at the Krystal Grand Hotel in Nuevo Vallarta, Mexico. Following an accidental clash of heads in the first round, the referee called a halt to the contest on advice from the ringside doctor at the end of round two, resulting in a second-round technical draw.[3][4]

In her next fight she faced Nancy Franco for the vacant WBC Silver female super flyweight title on September 25 at the Sports Arena in Pico Rivera, California. After unleashing a barrage of punches, referee Raul Caiz Jr. stepped in to call a halt to the contest at 1 minute and 20 seconds of the ninth round.[4]

Ruiz won the interim WBC female super-flyweight World title with a unanimous decision win over Sonia Osorio on 8 September 2022.[5]

She lost her title, and unbeaten record, to Ginny Fuchs by split decision at Dignity Health Sports Park, Carson, California, on 31 August 2024, with one judge scoring the fight 97-93 in her favour but the other two having it for Fuchs 97-93 and 100-90 respectively.[6]

Despite this loss, when injury meant Asley González was forced to vacate the WBC female super-flyweight title, Ruiz was given the chance to face Alexas Kubicki for the vacant championship at Save Mart Center in Fresno, California, USA, on November 29, 2025.[7] She won by unanimous decision.[8][9]
